ABSTRACT:
A swash plate type axial piston pump improved in respect to wear or abrasion-resistant capability of sliding members of the pump adapted to rotate relative to each other for protecting them from rapid wearing even upon high rotation of the pump. The axial piston pump includes a housing (1), a rotatable shaft (3) supported rotatably within the housing (1), an axial piston pump including a cylinder block (15) mounted on the shaft (3) axially slideably therealong and co-rotatably therewith and a plurality of pistons (21) accommodated axially reciprocatively within a corresponding number of cylinders, respectively, which extend axially, being arrayed around the rotatable shaft (3), a swash plate (23) disposed for moving reciprocatively the pistons (21) in axial direction as the shaft (3) is rotated, and a plurality of sliding members which are incorporated slideably relative to one another for constituting parts of the pump. At least one of the plural sliding members such as the valve plate (31), the cylinder block (15), the shoe (25), the swash plate (23), the shoe holder (27) and the supporting member (24) is coated with a nickel-phosphor-Teflon layer by plating.
